Value Collection 3SSC904F0204 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION 3SSC904F0204 is a 1/4-28 UNF hex head cap screw with a 2-1/4 inch length under head, manufactured from 18-8 stainless steel with no coating applied. The partially threaded shank provides a bearing surface for clamped joints where full thread engagement through the entire grip length is not required. This fastener suits mechanical assemblies, HVAC equipment panels, plumbing fixtures, and electrical enclosures where corrosion resistance is a priority. Installation is performed with a standard hex wrench or socket driver. The 18-8 stainless steel grade offers reliable performance in mildly corrosive and wet environments without surface treatment.

This screw is suited for light industrial and commercial applications requiring a fine-thread, corrosion-resistant fastener. Typical uses include securing sheet metal panels, pipe hangers, equipment brackets, and hardware in environments exposed to moisture or cleaning agents. The UNF 1/4-28 thread form provides finer thread pitch than standard UNC, giving increased thread engagement per inch and better resistance to vibration loosening in metal-to-metal assemblies.

Key Features

• 1/4-28 UNF thread for higher thread engagement and vibration resistance compared to coarse thread
• 2-1/4 inch length under head with partially threaded shank for clamped joint applications
• 18-8 stainless steel construction for corrosion resistance in wet or mildly chemical environments
• Uncoated finish preserves base material properties and avoids coating delamination concerns
• Hex head drive compatible with standard socket sets and open-end wrenches

Compatibility

Designed as an OEM-style replacement or stock fastener for equipment assemblies calling for a 1/4-28 UNF partially threaded hex head cap screw in 18-8 stainless steel.

Installation Notes

Install and torque using the appropriately sized hex socket or open-end wrench rated for the fastener diameter. De-energize all electrical panels and relieve system pressure before replacing fasteners on live equipment. Do not mix stainless steel fasteners with dissimilar metals in high-moisture environments without considering galvanic corrosion potential. Apply anti-seize compound if the fastener will be installed into aluminum or other reactive substrates.
